A foxy former NYU economics professor accused of stalking a senior Citigroup economist claims the finance honcho contacted her online – after he had her arrested.

Married moneyman Willem Buiter, 63, had an intimate two-year relationship with his ex-mistress Heleen Mees, 41, that eventually fizzled, defense lawyer Ira London said today in Manhattan Criminal Court.

Despite claiming that she began harassing him in 2011, London said that Buiter continued to correspond with her online well after that point.

“Mr Buiter admits he sent Miss Mees hundreds of emails after July 1st 2011,” he said as his client stood meekly beside him in a purple satin skirt and four inch gray stilettos. “(They) have been in contact on Skype as recently as June 19th.”

London even claimed that Buiter attempted to contact Mees online August 7th – after he had her arrested and he and his wife had restraining orders against her.

“The complainant attempted to contact my client on social media,” he said.

Manhattan Criminal Court Judge Joanne Quinones wasn’t pleased. “People, you are to admonish the complaining witness to not contact this defendant in any way,” she warned prosecutors.

But London admitted outside court that he was referring to a LinkedIn invitation from Buiter that might have been generated without the moneyman’s knowledge.

“She’s emotionally distraught about this,” London said. “She had feelings for Mr. Buiter and those feelings have been trampled.”

The leggy Dutch blood allegedly sent over 3,000 messages to the father of two including an image of herself masturbating as well as a vulgar message asking “Shall I lick your b—s?”

The persistent stunner even tried to access Buiter’s hotel room in Amsterdam last January by using a fake name at the front desk and sent 68 emails in a one-month period asking the Citibank bigwig out for a drink, court papers say.

When Mees didn’t get the reaction she wanted, she allegedly lashed out. “I hope you die (read this to your wife)” she allegedly e-mailed on one occasion.

After the scandal broke, Mees lost her NYU gig and is now interviewing for two positions elsewhere, her lawyer said.

The endless string of e-mails from Mees allegedly started in November of 2009 and continued up until her arrest on July 1st 2013.

Mees’ $5,000 bail was posted by a good Samaritan who read about her plight in the papers although she owns a $1.5 million coop in Brooklyn. London said she was considering returning the funds.
